Filed: 2021-04-19
Abstract: To provide information about communication quality according to movable objects existing around a travelling vehicle to be steered.SOLUTION: A plurality of people and various types of medical apparatuses exist in passageways and rooms of a medical institution. Such people, medical apparatuses, and the like may reflect or absorb radio waves used for wireless communication, thereby locally degrading communication quality of wireless communication. People and medical apparatuses are objects (referred to as movable objects) that can move to arbitrary positions, so it is difficult to predict their positions in advance. For this reason, it is also difficult to predict in advance positions where communication quality is degraded due to the movable objects. Therefore, the movable objects are recognized in real time from images captured by a travelling vehicle 10, and a degree of communication quality of wireless communication is determined according to the positions and number of recognized movable objects and an operator is notified of it. This allows the operator to remotely control the traveling vehicle 10 so as to avoid areas where communication quality is degraded.SELECTED DRAWING: Figure 1
